BACKGROUND

Although electronic wireless communications have been available for manydecades now, in a very short time in the not to distant past, every dayinteraction with devices having such capabilities has transformed fromlistening or watching the result of such technology at one's home tocarrying highly functional devices nearly everywhere one goes. Aswireless traffic has increased so to has the supporting technologies,especially in the realm of voice communications. However, the advancesin wireless technologies in the area of general informationcommunication has enabled the automatic exchange of information withoutthe need for constant user interaction. In so doing, various industrieshave made available wireless devices that automatically access wirelessnetworks, such as mobile or cellular networks, and automaticallyexchange information with other wireless devices. Thesemachine-to-machine (M2M) wireless devices can be allowed access to thewireless networks under the same protocols as cell phones. However, theease with which these M2M devices can be implemented and the variousdata collection functions they can serve has resulted in a proliferationof M2M devices, and correspondingly, an increase in the overall wirelesstraffic demands.

FIG. 1 illustrates generally a wireless network system 100, such as awireless mobile network, according to one embodiment of the presentsubject matter. In various embodiments, the wireless network system 100can include core network equipment 101, a base station 102 sometimesreferred to as a Node B or an enhanced or evolved Node B (eNB), and aplurality of devices 104, sometimes referred to as user equipment (UE),capable of communicating with or over the wireless network system 100 Incertain embodiments, a wireless network system 100 can include one ormore communication paths between the base stations 102, such as eNBs,independent of the core network equipment 101. In some embodiments, theUEs can include UEs capable of communicating automatically with otherUEs with little or no user intervention. Such UEs can be referred to amachine-to-machine (M2M) devices. A base station 102 and UE 104 canoperate as part of an LTE-A network, such as a radio-access network(RAN) or a UMTS network. The base station 102 and UE 104 can communicatewith each other using a plurality of channels. In various embodiments,the base station 102 and M2M capable UEs 104 can be configured tocommunicate orthogonal-frequency division multiplexed (OFDM)communication signals over a multicarrier communication channel. TheOFDM signals can comprise a plurality of orthogonal subcarriers. In somebroadband multicarrier embodiments, base station 102 can be part of abroadband wireless access (BWA) network communication station, such as aWorldwide Interoperability for Microwave Access (WiMAX) communicationstation. In some other broadband multicarrier embodiments, base station102 may be a 3rd Generation Partnership Project (3GPP) UniversalTerrestrial Radio Access Network (UTRAN) Long-Term-Evolution (LTE) or aLong-Term-Evolution (LTE) communication station, although the scope ofthe invention is not limited in this respect.

For more information with respect to the IEEE 802.16 standards, pleaserefer to “IEEE Standards for Information Technology—Telecommunicationsand Information Exchange between Systems”—Metropolitan AreaNetworks—Specific Requirements—Part 16: “Air Interface for FixedBroadband Wireless Access Systems,” May 2005 and relatedamendments/versions. For more information with respect to UTRAN LTEstandards, see the 3rd Generation Partnership Project (3GPP) standardsfor UTRAN-LTE, release 8, March 2008, including variations andevolutions thereof.

In some embodiments, the base station 102 and the UEs 104, such as M2Mdevices, can utilize one or more antennas for transmission of RF signalsbetween the UEs 104 and between the UEs 104 and the network. In certainembodiments, the antennas can comprise one or more directional oromnidirectional antennas, including, for example, dipole antennas,monopole antennas, patch antennas, loop antennas, microstrip antennas orother types of antennas suitable for transmission of RF signals. Invarious embodiments, instead of two or more antennas, a single antennawith multiple apertures can be used. In these embodiments, each aperturecan be considered a separate antenna. In some multiple-inputmultiple-output (MIMO) embodiments, antennas can be effectivelyseparated to take advantage of spatial diversity and the differentchannel characteristics that can result between each of antennas and theantennas of a transmitting station. In some embodiments, a UE 104, suchas an M2M device, can utilize a single antenna.

In various embodiments, the eNB or network resources associated with theeNB can monitor the network traffic and can modify parameters of the eNBor the UEs to utilize the network resources such that disruptions tonetwork access is minimized and that high priority communication overthe network is maintained. In various embodiments, the eNB or otherresource can detect an overload condition of the network, or theprobable future overload of the network. In such embodiments, the eNB orother network resources, such as the core network equipment, can providecommands, messages or changes to system parameters, communicated overthe network, that bar one or more UEs from accessing the wirelessnetwork system.

FIG. 2 illustrates generally an example of a UE 204 including aprocessor 210, transceiver 211, and an antenna 213. In some embodiments,the UE 204 can include memory 214 to store processing information andparameters. In certain embodiments, the UE can accommodate removablememory 215 such as a system identification module (SIM), for example. Incertain embodiments, the UE can include a power source 216 to allowmobile or remote operation. In some embodiments, the UE can includeinputs and outputs. In certain embodiments, the UE inputs can include asensor 217, such as, but not limited to, a temperature sensor, a modulefor detecting GPS position, a medical sensor, a condition detector suchas a voltage, current, liquid or gas flow detector, a liquid or productlevel sensor, a light sensor, a infrared (IR) sensor, a clock, a switch,or a counter. In certain embodiments, the UE outputs can include, butare not limited to, a light, a vibration device, a voltage output, anelectrode, or an actuator 218, such as a solenoid or motor. In certainexamples, the UE can include user inputs and outputs (I/O) 219 such as,but not limited to, a keyboard, a display, a microphone or a speaker. Insome embodiments, such as simple M2M devices, the processor 210 caninclude circuitry to perform the functions of the device in contrast toa microprocessor based processor.

Access Class Barring (ACB) is a known operation in mobile networks,whereby devices of certain classes can be barred from using definedresources so that other devices can be provided priority. At present,access class barring is geared towards distinguishing access controlbetween a mobile assigned an access class for “normal” uniform accesscontrol treatment (0-9) and higher priority classes. These classes weredefined when essentially all devices were used by human operators, anddid not anticipate the rise of machine-to-machine (M2M) operation.Accordingly, the current specifications related to ACB mechanism lackmechanism to differentiate between M2M devices and human operateddevices. As such, there is a lack of procedures that can be directed tosending messages and instructions exclusively to M2M devices.

In addition, responsive speed of current ACB mechanisms can often be toslow to mitigate network congestion because such mechanisms utilizesystem information messages that are subject to modification proceduresthat can be relatively extensive compared to the rate of increasingnetwork congestion at the time of detection. For example, a currentapproach for ACB includes changing parameters associated with systeminformation block 2 (SIB2) or a system information block of type 2. Incertain protocols, two modification periods can be required to changethe access behavior of UE upon receiving a system information messageindicating a change in an ACB parameter. Such modification periods caninclude a system information block (SIB) modification period and an SIBupdated information period. The total time to implement the change inthe ACB parameter can be lengthy, for example a modification period canextend as long as about 41 seconds in some situations.

As more devices, both human operated and M2M, are added to mobile devicenetworks, the likelihood of congestion on the radio access channelsincreases. Many M2M devices are used for automated reporting of valuesto a centralized system. The spectrum of M2M devices is extremely wideand varied. Such devices can include, but not are not limited to, smartmeters for the electrical grid and other utilities, smart sensors,medical devices for mobile health and telemedicine, for example, remotemonitoring and control devices for vending machines, vehicles, signage,and asset tracking. Though timely access to the wireless network isdesired for M2M communications, M2M communications of some UEs can bedelayed access to a congested network without compromising the functionassociated with the delayed M2M communications. Meanwhile, users ofnetwork devices, such as voice users, can be inconvenienced by congestednetworks that can disconnect or refuse access temporarily while M2Mdevice communications are allowed to contribute to the congestion eventhough the M2M communications are not time critical. Without the abilityto treat M2M devices differently than user operated devices, as loads ona network increase, an M2M device that does not depend on timely accessto the network can be treated the same as a user operated device. Byproviding a mechanism to differentiate M2M devices from other networkdevices, the occurrence of large scale network congestion can bemitigated.

In various networks, M2M UEs can cause bursty access. For example, M2MUEs can include devices that have scheduled update periods. Because ofsimplicity in programming such UEs, those update periods can beprogrammed to occur at the same interval or at intervals that haveoverlapping update times with other UEs, such as at the top of an hour.When a surge of M2M devices suddenly access the network for a shortperiod, for example between 10 and 60 seconds, the modification periodsof the current solutions, as discussed above, may not be helpful inalleviating the network congestion. In addition, although some eNBs canstill have additional methods for overload handling, such as radioresource control (RRC) rejection, such methods may not fulfill thenetwork overload protection purpose because the random access channel(RACH) can be overloaded thus blocking access of other UEs for asubstantial period of time. In addition, RRC rejection may not fulfillthe network overload protection purpose because RRC signaling messagescan use a large number of radio resources thus impacting quality ofservice of ongoing connections of other connected UEs.

The present subject matter provides apparatus and methods of enhancedaccess barring EAB that can be implemented in UEs in a more timely andefficient manner to make access barring more effective. In an example, apaging message can include a notification indicating a change in EABparameters. Upon detecting the notification, the UE can obtain updatedEAB parameters and apply the appropriate access control without waitingfor an SIB modification period. In an example, the UE can include one ormore settings identifying the UE as a member of one or more categoriesof device. In an example, the one or more settings identifying the UE asa member of one or more categories of device can be saved in asubscriber interface module (SIM) of the UE. In certain examples, theone or more categories associated with EAB are different than the one ormore classes associated with ACB.

In an example, a UE having machine type communications (MTC) capabilitycan be a member of one of several categories of M2M devices that caninclude lower priority MTC communications. In an example, lower priorityMTC communications can include scheduled communications to transmitroutine status or control information. In an example, such as forcertain medical device UEs, a device can be a member of a categoryindicating a need for higher priority MTC communications. In certainexamples, high priority MTC communications can include communications toreport or control warning conditions or conditions that can indicate athreat to the health of equipment or personnel.

In certain examples, a paging message from a cell base station canmitigate congestion on a mobile device network because the message canbe received and processed before or as the network congestion begins toincrease.

In an example, the page message can include the EAB information. In anexample, the paging message can include a notification of a change inthe EAB information. In response to receiving the page message, the UEcan access previously stored EAB information or can receive additionalmessages, such as a system information message, with the EABinformation. In certain examples, previously stored EAB information caninclude default EAB information stored well before the UE received theEAB notification. In some examples, the previously stored EABinformation can include EAB information that was transmitted just priorto or simultaneously with the EAB notification. In an example, uponreceiving a page message including a notification of a change in EABinformation, the UE can subsequently receive the EAB information insubsequent message such as a subsequent system information message or asubsequent page message. In certain examples, a UE can apply barringpolicy established by the EAB information received with or in responseto an EAB notification until a subsequent page message, including a newEAB notification, is received. In an example, a UE can apply barringpolicy established by the EAB information received with or in responseto an EAB notification until a predetermined interval of time expires.In an example, the predetermined interval of time can be determinedusing the received EAB information. In an example, a UE can applybarring policy established using the EAB information until new EABinformation is received at the UE.

In certain examples, a UE can access a system information blockincluding the EAB information each time the UE attempts to accesses themobile wireless network. In an example, a system information blockincluding the EAB information can be accessed without substantial delay.In an example, a system information block including the EAB informationcan be accessed and the EAB policy established by the EAB informationcan be implemented in the UE within a predetermined period of time. Incertain examples, the predetermined period of time to access the systeminformation block including the EAB information and to apply the EABpolicy at the UE can be less than about 1 second. In an example, thesystem information block including the EAB information is different thana system information block including the ACB information. In an example,a device of the UE, such as one or more processors, can request accessto the mobile device network. As part of the process of accessing themobile wireless network, the one or more UE processors can access thesystem information block including the EAB information to determinewhether the UE is a device in a category of devices barred fromaccessing the wireless mobile network. If the UE is of a category ofdevices barred from accessing the mobile device network, the one or moreprocessors can deny the request to access the mobile device network. Ifthe UE is not of a category of devices that are barred from accessingthe mobile device network, than the one or more processors can grant therequest to allow the UE to access the mobile device network.

FIG. 3 illustrates generally a message flow diagram 300 between a basestation 302 and one or more MTC UEs 304 of an example mobile wirelesssystem. In certain examples, upon detection of network congestion 330,or a threshold probability of network congestion, network resources,such as but not limited to, core network equipment, and radio accesstechnology equipment such as a mobile management entity (MME), radionetwork controller (RNC), radio resource control (RRC), or radioresource management (RRM), can provide command information to implementEAB. In certain examples, the network resources can determine one ormore categories of UE equipment to bar access to the mobile devicenetwork. In certain examples, command information can be received fromnetwork resources at one or more base stations 302, such as one or moreeNBs or HeNBs. In certain examples, upon receiving the commandinformation, a base station 302 can wirelessly transmit a message 331,such as a page message, providing the EAB information using the mobiledevice network. In some examples, upon receiving the commandinformation, the base station 302 can wirelessly transmit a message 331,such as a page message, providing an EAB notification using the mobiledevice network. In such an example, the base station can wirelesslytransmit another message 332 including the EAB information. Thesubsequent message 332 can include, but is not limited to, a pagemessage or a system information message. In certain examples, a UE 304can apply barring policy established by the EAB information receivedwith or in response to an EAB notification until a second subsequentmessage 340, including a new EAB notification, is received. In anexample, a UE 304 can apply barring policy established by the EABinformation received with or in response to an EAB notification until apredetermined interval of time expires. In an example, the predeterminedinterval of time can be determined using the received EAB information.

In an example, a device of a UE 304, such as one or more processors, canrequest access to the mobile device network. As part of the process ofaccessing the mobile wireless network, the one or more UE processors canaccess the system information block or other parameter including the EABinformation to determine whether the UE is a device in a category ofdevices barred from accessing the wireless mobile network. If the UE isof a category of devices barred from accessing the mobile devicenetwork, the one or more processors can deny the request to access themobile device network while the enhanced access barring of the UE isactive 333. If the UE is not of a category of devices that are barredfrom accessing the mobile device network, than the one or moreprocessors can grant the request to allow the UE to access the mobiledevice network 334.

It is understood that the subsequent message 332 can be optional if theinitial message 331 includes the EAB information. It is also understoodthat the second subsequent message can be optional if the expiration ofthe EAB information is predetermined

In an example, the EAB information canbe included in a system information block. In an example, the systeminformation block can be different than a system information blockincluding ACB information. In certain examples, a UE 304 can applybarring policy established by the EAB information received with thesystem information message 431 until a subsequent system message 340including a new EAB notification, is received. In an example, a UE canapply barring policy established by the EAB information received withthe system information message 331 until a predetermined interval oftime expires. In an example, the predetermined interval of time can bedetermined using the received EAB information.
